shadow28 Posted May 4, 2004 Report Share Posted May 4, 2004 I have a 90 granprix with 204,000 miles my wife wants me to put it to rest because of this problem. My problem is sometimes the car will not start unless I press the gas pedal a little. Once it running the engine runs great until you come to a complete stop, then it starts to sputter and stall. Sometimes I can catch it. I changed the spark plugs,wires, iac and used sea foam for the injectors. Willing to try anything to keep my baby. Thank for time Ray Quote Link to comment Share on other sites More sharing options...
DaveFromColorado Posted May 4, 2004 Report Share Posted May 4, 2004 are you getting any codes? I'd almost guess the TPS may be out of range, but without seeing the car, it'd be really hard for me to help ya out. --Dave. Quote Link to comment Share on other sites More sharing options...

DaveFromColorado Posted May 4, 2004 Report Share Posted May 4, 2004 did you check the ohm load on 'em and replace only the ones you needed to replace, or did you just replace all of 'em... --Dave Quote Link to comment Share on other sites More sharing options...
91oldscutlass Posted May 4, 2004 Report Share Posted May 4, 2004 Dave, there was nothing going through all of them....It wouldnt even try to fire at all. I figured just place all of them then I knew what I had. Quote Link to comment Share on other sites More sharing options...
GnatGoSplat Posted May 4, 2004 Report Share Posted May 4, 2004 Have you tried the extended idle learn procedure? If the car runs and drives fine for the most part, the ECM may be having trouble controlling the IAC. Quote Link to comment Share on other sites More sharing options...
DaveFromColorado Posted May 4, 2004 Report Share Posted May 4, 2004 Ahh, my beretta needed two injectors, before I replaced 'em it wouldn't start (easily) but it never sputtered before it died, it'd just die at random. anyhow, back to the orignial topic... it sounds like there's a fueling problem, first I'd check the fuel pressure at the rail, then check the fuel pump, and the fuel filter, because those may be causing the issues, or if the regulator isn't holding any pressure in the rail, that too could cause the issue ... I hope any of those ideas help ya out. --Dave. Quote Link to comment Share on other sites More sharing options...
shadow28 Posted May 5, 2004 Author Report Share Posted May 5, 2004 Thanks for the help. My iac was out to far. I measures the 1.125 from the oil ring not from the base. Thanks again, Ray Quote Link to comment Share on other sites More sharing options...
